Abstract— We obtain formulas for the midpoint and quasimidpoint of parabolic and nonparabolic segments in the canonical frame of the second type on the extended hyperbolic plane \(H^2\) whose components in the projective Cayley–Klein model are the Lobachevsky plane \(\Lambda^2\) and a positive-curvature hyperbolic plane \(\widehat{H}\). We propose an algorithm for the Chaos game in the \(H^2\) plane and present the results of this game played with the prepared software package pyv on triangles in the \(\Lambda^2\) plane and trihedrals in the \(\widehat{H}\) plane.

Keywords: extended hyperbolic plane, Lobachevsky plane, hyperbolic plane of positive curvature, fractal, Chaos game, Sierpinski triangle
